To all whom 'it may concern:

Be it known that I, RUDoLF PLANCKH, a subject of the Emperor of Austria-Hungary, and resident of Graz- Eggenberg, Austria-Hungary have invented certain new and useful Improvements in a Boiling and Distilling Apparatus, of which the following is a specification.

The present invention relates to improvements in a boiling and distilling apparatus.

The invention consists of the combination of several apparatus for exchanging heat to the fluid for distillation in such a way, that the fluid, which comes from the reservoir goes through heated condensing apparatus in which it evaporates into a second heat exchanging apparatus from which it goes into a superheater and compressor where after further heating it goes through the same apparatus in a different manner, transferring its heat to the rising fluid, leaving as cooled distillate.

The drawing gives diagrammatic view of two forms of construction of the invention.

Figure 1 shows how a compressor is employed for superheating, and Fig. 2 shows how an injector, which is fed with high tension steam, is employed for the same purpose.

The improvements consist in the combination of several apparatus in such a way that the fluid which comes from the reservoir a into the serpentine pipe 0 evaporates into the apparatus d, owing to the heat conveyed to it by the distillate, from which, after further heating, it goes into the serpentine e which is in the superheaterf from which it is compressed into the first apparatus b by the compressor y through the pipe h whereby the fluid in the apparatus receives the heat while the distillate goes out through the pipe i as cooled distillate. In order that the gases, such as air, carbonic acid and the like, which arise during the heating of the fluid, may escape vents k are arranged in suitable places.

In the second form of construction; instead of a superheater an injector Z which is fed with high tension steam is employed which is adapted to superheat the evaporate coming from the pipe m.

If it is intended not to let the fluid evaporate but only give it a certain high temperature, only one apparatus is arranged, and in this case the compressor can be dispensed with.

I claim:

In a boiling and distilling apparatus, the combination of a tank a, a tube fixed at the bottom of this tank, a serpentine pipe 0 the lower end of which is connected with the lower end of the said tube, a casing enveloping the said serpentine pipe 0, a casing 11 connected with the upper end of the said serpentine pipe 0 by a tube, a serpentine pipe h in the said casing 11 connected by its lower end to the upper part of the casing b, a super-heater 1' containing a tube 0 connected with the upper part of the casing (I, and a suitable compressing device connectcd by a tube with tube 0 and with the upper part of the said serpentine pipe It, substantially as shown and described.
